Bridging the Gap Between Ex Nihilo and GregTech
Minecraft modpacks that lean into technological progression often face a tricky balancing act. On one side, you have the skyblock classic Ex Nihilo, which lets you generate resources from nothing by sifting dirt, gravel, and dust. On the other, there is the industrial behemoth GregTech, a mod that redefines complexity with its intricate ore processing chains and demanding power systems. Left unchecked, the two can clash: Ex Nihilo’s simple resource output can bypass GregTech’s carefully tuned early-game grind, while GregTech’s machinery can render Ex Nihilo’s manual sieves obsolete in an unbalanced way. ExGregilo is the mod that steps in to harmonize these two worlds, ensuring that skyblock and survival packs feel cohesive rather than contradictory.
What Exactly Is ExGregilo?
ExGregilo is a compatibility addon designed to sit between Ex Nihilo and GregTech 5 Unofficial. It does not introduce standalone content but instead rewires the interaction between these two giants. The core idea is simple: replace the standard ore outputs from Ex Nihilo’s sieves with GregTech crushed ores, and then provide GregTech-style machines to automate the entire sifting process. This means every nugget, dust, and impure pile you obtain fits naturally into GregTech’s elaborate ore processing chain, rather than giving you finished ingots that skip half the tech tree.
Key Features That Reshape Early Game
ExGregilo’s feature set is focused but transformative. It touches three main areas:
- Ore Output Overhaul: The standard sieve drops are replaced with GregTech crushed ores, which must be washed, centrifuged, and smelted just like any other GregTech ore. This forces players to build proper ore processing setups even when using skyblock resource generation.
- Advanced Sieve with Replaceable Meshes: A new sieve block accepts different mesh tiers, allowing faster sifting as you progress. This bridges the gap between the early manual sieve and full automation, giving a tangible sense of acceleration without breaking balance.
- GregTech Auto Sieve Machine: A dedicated single-block machine that consumes EU power to sift materials automatically. It integrates directly with GregTech’s energy net and can be upgraded with overclocker modules, making it a natural fit for any GregTech production line.
Compatibility and Version Requirements
ExGregilo is not a standalone mod. It requires both Ex Nihilo and GregTech 5 Unofficial to function, and the version pairing is strict. The mod will not work with the original GregTech 5; only the Unofficial fork is supported. Additionally, the version of ExGregilo you use must match your GT5U build precisely:
- ExGregilo 1.0.3 works only with GT5U version 5.09.26 or higher.
- ExGregilo 1.0.2 is required for GT5U versions 5.09.21 and below.
- GT5U versions 5.09.22, 5.09.23, and 5.09.24 are not supported by any release of ExGregilo.
This tight coupling exists because the mod directly references GregTech’s internal ore dictionary and machine recipes, which changed significantly between those builds. Using the wrong combination will result in missing items, broken recipes, or outright crashes. Always double-check your GT5U version before adding ExGregilo to your instance.
Why Disable Other Auto-Sieves?
One of the more aggressive design choices in ExGregilo is that it deliberately removes the auto-sieve recipes from Ex Compressum and Ex Astris. The reasoning is straightforward: those mods provide RF-powered sieves that are far too cheap and fast compared to GregTech’s progression curve. In a pack where GregTech is the central tech mod, having a low-cost RF sieve that churns out ores with minimal infrastructure undermines the entire early-game challenge. ExGregilo’s own auto sieve requires EU, proper voltage tiering, and the same kind of resource investment you would put into any GregTech machine. This keeps the power curve consistent.
Similarly, items like Extra Utilities generators can trivialize GregTech’s energy economy. ExGregilo does not disable them automatically, but the mod author strongly recommends using MineTweaker or similar tools to remove or rebalance any RF-based power generation if you want a pure GregTech experience. Without such adjustments, you might find yourself bypassing steam and combustion ages entirely, which defeats the purpose of playing with GregTech in the first place.
Progression and Practical Use
In a typical skyblock pack featuring Ex Nihilo and GregTech, your early hours are spent hammering cobblestone into gravel, sifting it by hand, and painstakingly collecting tiny ore pieces. ExGregilo doesn’t eliminate that grind but makes it feel more purposeful. The crushed ores you obtain must be washed in a GregTech ore washer, then centrifuged or thermal centrifuged, and finally smelted. This means you need to build actual GregTech infrastructure before you can turn sifted materials into usable ingots. The advanced sieve with replaceable meshes gives you a stepping stone: you can craft better meshes as you unlock new materials, increasing yield and speed while still operating manually. Once you reach the LV age and can supply steady EU, the auto sieve machine takes over, letting you scale up resource generation just as you would scale up any other GregTech process.
For players who enjoy tinkering with mod configurations, ExGregilo’s source code is available under the GPLv3 license, and the author welcomes bug reports, feature requests, and texture submissions through the issue tracker. This open approach has helped the mod stay relevant in the ever-shifting landscape of GregTech 5 Unofficial updates. If you are assembling a modpack and want to ensure that Ex Nihilo and GregTech work together rather than against each other, installing ExGregilo via a modern launcher like foxygame.net makes the process painless—you can browse, download, and activate the mod directly from the launcher’s interface without hunting through forums or worrying about manual file placement.
Balancing Your Entire Pack
ExGregilo solves the ore generation mismatch, but a truly balanced GregTech experience requires attention to other mods as well. Any mod that provides easy RF power, simple ore doubling, or free resources will feel out of place. The mod author recommends using MineTweaker or CraftTweaker to adjust or remove problematic recipes. For instance, you might disable the Ex Compressum auto hammer and auto sieve entirely, since GregTech offers its own maceration and now, with ExGregilo, its own auto sieve. You could also gate Extra Utilities generators behind higher-tier materials or remove them altogether. The goal is to make every resource flow through GregTech’s demanding but rewarding pipeline.
Conclusion
ExGregilo is a niche mod with a very specific mission, but for the right pack, it is indispensable. It transforms the chaotic intersection of Ex Nihilo and GregTech into a smooth, logical progression where skyblock resource generation feels like a natural extension of GregTech’s ore processing. The strict version requirements and the removal of competing auto-sieves might seem harsh, but they are necessary to preserve the challenge that GregTech players seek. If you are building a GregTech 5 Unofficial skyblock or survival pack and want every aspect of resource acquisition to respect the tech tree, ExGregilo is the missing link. Just remember to pair it with the correct GT5U build, disable conflicting RF mods, and embrace the long but satisfying road from manual sifting to a fully automated, EU-powered ore factory.
